Benefits of technology

Enables extended operation of electronic devices beyond internal battery limitations by providing externally supplied power and mitigating battery degradation through controlled air access, enhancing discharge performance and energy density.

Problems solved by technology

Unfortunately, the inclusion of these features usually places additional demands on the rechargeable batteries that power the cell phones.
The net result is that the cell phones' run times become shorter and shorter due to the increased power demands.
The existence of these two trends (i.e. increased electrical demand and reduced battery size) has caused many cell phone users to experience a failed telephone call or data transmission due to the depletion of their phone's battery at an inopportune moment.
An additional trend that complicates resolving this problem is that most cell phones require a battery that has specific size and shape characteristics.
Furthermore, the recharging port built into the cell phones can limit the type of charger that can be connected to the cell phone.
Collectively, these factors limit the consumer's ability to rapidly replace the depleted battery with another power supply.

Embodiment Construction

[0014]Embodiments of the present invention facilitate electronic device operation by providing externally supplied power. As a result, electronic devices can be operated for extended periods of time, which exceed limitations of internal batteries.

[0015]FIGS. 1A, 1B, 1C, and 1D are diagrams that illustrate a use extender device 100 in accordance with an embodiment of the present invention. The use extender device 100 can be employed to supply power to a separate electronic device generally shown at reference identifier 1000, such as a cellular phone, portable multimedia device, personal digital assistant (PDA), notebook computer, and the like. The use extender device 100 can facilitate operation of such electronic devices by extending operation times beyond that of internal batteries provided inside the electronic device.

[0016]The device 100 includes a housing 102 and a connector 104, according to one embodiment. The housing 102 includes a top cover 108 and a bottom cover 106. The to...

Abstract

The use extender device (100) and method (700) thereof is provided, wherein the device (100) includes a housing (102) with a top cover (108) having a back side wall, front side wall, and lateral side walls. The device (100) further includes a bottom cover (106) operably attached to the top cover (108), and a battery cavity (130). The housing (102) can also include a circuit board cavity (116) defined by at least one of the top cover (108) and the bottom cover (106), a closing mechanism (114) attached to the top cover (108) and removably attaching the top cover (108) to the bottom cover (106), such that the battery cavity (130) is accessible, and at least one aperture (110) defined by at least one of the top cover (108) and bottom cover (106), wherein air flow into the battery cavity (130) is regulated by the aperture (110).

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of International Patent Application No. PCT / US2008 / 052065, filed Jan. 25, 2008, and designating the United States, which claims the benefit of U.S. Provisional Patent Application No. 60 / 897,407, filed on Jan. 25, 2007, the entire disclosures of which are hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention is related generally to electronic devices and, more specifically, to devices and methods related to supplying power to electronic devices external to the device.BACKGROUND OF THE INVENTION[0003]The proliferation of portable battery powered devices, such as cellular telephones, has increased dramatically in the last several years and this trend is expected to continue. The phones typically use a rechargeable battery that is built into the phone to provide the needed power. The length of time that the battery powers the phone is dependent primarily upon the size of the batte...
